Measurements of a production Sony 500ES OOTB after basic set up with about 15 hours on the bulb, taken with a Discus trained to an i1pro2 (SXRD profile) using Calman Professional V5.2.
Rec-709, D65, Gamma 2.4 selected in the user profile. Dynamic Iris set to off during the measurements (set to limited during viewing). Max brightness set to 0 to get around 18fL.
Brightness and contrast checked (no clipping/crushing), RC lowered to 0 and sharpness to 10. Screen is a Carada BW 88" diag 16x9 with a real gain of 1.1.
All dEs under 3 for greyscale/gamma and color checker
All dEs under 3 for gamut saturation and luminance linearity tracking. Average dE around 1.7.
All the 125 points of the control points of the 5x5x5 cube for the Radiance (without any calibration) average to 1.7. Max dE of 3.2.
I'm happy to see that I can still trust my eyes
I have no idea which meter or which screen was used in the review linked above but as far as I'm concerned, the colour accuracy of this display OOTB with a colour-neutral screen is truly amazing, and Sony should be commanded for it.
Now the error margin of the i1pro2 I used as a reference to train the Discus could be anything between 1 and 5 dEs. There is no way to know, as it's not a reference meter calibrated and certified in factory as such, except that I believe it is closer to 1 than to 5, otherwise I would see it.
I could get the color performance of the 500ES closer to my i1pro2 and get nicer looking charts to show off, but I would have no idea if the actual picture is closer to reference, or further away.
This is what I meant when I said beware using non reference meters with this display (those who know me know that it's the first time I ever said such a thing).
Those who want to calibrate a projector that tracks as well as this one out of the box, as measured by non-reference semi-professional meters, are more than welcome to use a cheap meter to improve their graphs
Just remember to look at the picture, and to compare before and after. The likelihood of making the picture worse with a DIY calibration is a reality with these displays, especially if you don't really know what you are doing (for example if you don't switch the auto-iris off and launch an autocal).
Personally, I wouldn't even attempt to calibrate it with my Discus trained to my i1pro2, at least not out of the box with such pre-cal results. I would need a Jeti 1211 to train a Klein K-10, at a minimum, if I wanted to be sure to improve things and not make them worse.
If the bulb or the panels drift with time, or if the screen is not as color neutral as my Carada BW, then of course a calibration (especially a good cube calibration) will improve things, but not until the dEs reported are above the error margin of the equipment used to calibrate.
The purpose of display calibration is to bring the picture closer to reference, not to bring the charts closer to reference
I'm under an informal non-disclosure agreement and I'm running out of time so I won't comment any further about the display or its performance, or about calibration in general, but I just wanted to illustrate what I was saying earlier about the OOTB colour accuracy of this display with hard data.
If you still have doubts, this will hopefully soon be confirmed by someone you trust, who uses reference measuring equipment.
